DEMOUNTABLE RIM FOR AUTOMOBILE-WHEELS.

T all'whom it ma concern: Be it known that I, ERLE K. BAKER, a citizen of the UnitedsStates, and a resident of Chicago, county ofCook,-and State of Illinois, have invented certain new and useful Improvements in Demountable Rims for Automobile-Wheels, of which the follow ing is a specification. I

My invention relates to demountable tire- .carrying rim constructions for automobile wheels, and has special reference to improvements in and upon demountable rims of the transversely split and-bolted-on type. An object of my invention is to provide a demountable rim of more simple construction and of lower cost than any now in use;

which more easily may he placed in and taken from a pneumatic tire; and which may be used interchangeably upon most automobile wheels now in use.

A further object of my. invention is to dispense with the many parts which are now used to connect the ends of such a rim and in place thereof substitute a construction which preferably shall serve all the purposes of a spacer, a connector, an aliner, a driver,

and a valve stem container, -whereby the construction of the rim may be greatly sim-.

mounted upon a demountable rim embodyingmy invention; Fig. 2 is an enlarged ver-. tical and longitudinal section of the wheel, rim and tire, adjacent the valve stem; Fig. 3, is a similar sectional view illustrating a modified form of my invention; Fig. 4, is an outer side view of the rim ends of the accompanying structure illustrated in Figs. 1 and 2; Fig. 5, is a sectional view on the line 5-5 of Fig. 2; Fig. 6, is a sectional view on the line 6-6 of Fig. 2; and, Fig. 7, is an outer side view of the rim ends and accompanying parts shown in Fig. 3. i

. Specification of Letters Patent. Application filed March 10,1914. Serial No. 823,806.

' Patented May 25,1915.

In these drawings I have shown a typical automobile wheel having a wooden felly 2 and a metal felly band 3. The latter may be provided with the usual inner-side flange or other projections (not shown) against which the rim 4 is thrust and held by bolt-. actuated wedge-lugs 5, of usual. construotion. My inventionis not limited to the combination of the metal felly band and wooden felly,-for an all-metal construction of the same general form and purpose may be substituted; and where the words felly. band appear hereinafter theyare usedin this inclusive sense. a

The felly band, as well shown in Fig. 2, is provided with a large valve-stem-opening 6, surrounded by an upstanding or ,outstanding -fiange 7 formed from the felly band itself.- This flange 7 constitutes a" spacer upon which the rim rests as shown in Figs. 1, 2 and 3. The hole 6 is consider ably larger than the valve stem 8 to permit the easy placement of the stem and rim on the wheel. Most automobile wheels of present day construction which carry rim secur- 0 ing wedge-lugs, have valve holes thus proportioned to the valve stem. The demountable rim, as here shown, has integral flanges 8, 8 shaped to receive a straight-side pneumatic tire. In lieu of such flanges, integral clencher flanges may be used. And one or both flanges of the rim may be detachable from the body of the rim in well known manner, and not' aflect the operation or utility of the herein described invention. The riin is split or cut apart at one point' on a transverse line. Thus, 9 represents the split in the rim, and 4: is one end of the rim and 49 the other. I prefer a diagonal split,

as shown inFigs. 4, 5 and 7, the same being of the kind and for the purpose set forth in application Serial No. 502,069, liled June 1%, 1909. Y 1 The tire 10 is seated on the rim 4 and it IS customary to keep the tire inflated thereon whether or not the rim in position on the wheel. The pressure of the inflated tire tends to collapse the rim. The pressure of the wedgelugs tends to expand the rim. To overcome both tendencies I employv a construction at the split 9 in the rim, which as about to be described, preferably and conveniently serves many.pur'poses.

I first make an endless rim 4 of desired cross section. Then I punch a hole therein andformor press a circular flange A from the body of the rim around said hole. In this manner I provide an annular (lIlVliIj upon the inner periphery of the rim. This driver or integral sleeve is of a size to fit Within the spacer and valve stem holeprojection 7 of the telly band, as shown in Fig. 2, and therefore serves to hold the rim againstrotation on the wheel when placed thereon and secured by the Wedge-lugs 5. The hole A Within the driver -is considerably larger than a valve stem to allow room for a valve stem container or bushing 11 about to be described. Having formed this integra l. driver flange saw ,or otherwise cut the rim apart on a line that intersects the opening A. The. cut obviously, divides the flange into a major part 4 on the end 4:? of the rim and a minor part i" on the rim. end 4*. But this division of the flange does not lessen its usefulness as a (lil."l'

when the two parts are confined in the valve stem hole 6 of the felly band. On the contrary the divided'flange,takeson another function; that is, when thus confined the two parts serve to lock the rim. ends El, 4: together. and in alinement.

As it desirable to protect the Valve stem when the rim ends are separated, as in plac-- ing the rim in and taking it from a tire, I

prefer to add a member 11 which will provide the protection and at the same time serve an. interlock between the rim ends, to hold them in alinement. This member 11, as shown, is a short'sleere or bushing preferably somewhat longer than the integral sleeve A and which I swage or weld within. thepart elf but not in the minor part l". Thus I *prdvide a projection 11 on the rim end 4 thatfits the recessin the part 4:". In this manner the rim ends are separably but etl'ectuallyinterlocked and held in alinement against forcotending to clisaline them While.

oli' the wheel. The relations of the several parts are clearly shown in F 2, 4, 5 and 6. If desired the swag'e bars 11*, 11" upon the bushing maybe removedwhere they lap upon the rim end i, as indicated in Fig. l, but in most cases it is desirable to merely blunt them and leave themto interlock with .the QEXPOS GK'l endsof the bushing, as indi cated in Fig. 2. The bushing is In re enough "fto l osely contain the valve stem, see dotted lines Fig. 2, and being positioned directly at the split in the rim it is obvious that the" spreader (not shown) of the valve stem bridges both the bushing and the silit and protects the inner tube (not sliownl tire from. both.

To disengage the ends of the rim for the purpose of-removing it from or placing it in a tire, it is only necessary to force the end 4.3T past the interlocking l mshingin transverse direction or to "force the end (P in- 'ward, toward the center of the rim, and

Aon the rim, I then of the in a divided hole in the rim as shown in Figs. 3 and I. In each case'tlie bushing enters the hole 6 in the folly band, as one part of the driver and a. second driver stud 13, on the other end of the rim enters a second hole 14 in the folly band. I

As used in theappended claims the Word rim incense-a siuta-bly flanged, tire-carrylng, demouiitable wheel. rim; and, thehword ely split-contaming" a transverse split.

While I have illustrated and described my v invention in accordance with the patent stat" utes, I desire it to be understoodthat thede" tails 0t construction may be materially varied llltl'lTlHtt'VlHlOllS changes, modifications and substitutions may be made, in. thedemounta le rim herein illustrated without (le' parting" from the spirit and scope of my invention asset forth'in theappended claims.
